I had a notification on my banking app asking me to authorise a transaction, at the same time I received a call from my banks fraud team saying there was suspicious activity on my account, he confirmed my name, address and DOB to me and didn't ask for any other details other than a security code.
I was in the middle of trying to get my children out of the car and stupidly gave him the code which of course has turned out to be an OTP code. I didn't read the message properly as I was flustered and in a rush. He then phoned back a short while later and asked me to go through security with a code again and again I gave him the code.
I realise I am so incredibly stupid, I've been crying about this all weekend at my stupidity.
The two transactions have amounted to 10k and have taken my savings. Everything I have. I have of course now reported it to my bank who have blocked everything, including my online banking and now I have to wait for an investigation to take place.
I fear I won't be refunded because I was so stupid.
My only hope is that I went on to the app and declined a payment as not being me, and I hardly ever use the account so why did they allow these big payments to go through? I know they had the OTP code but I had declined an identical transaction on my app... maybe I'm clutching at straws 
Has anyone done anything similar and got their money back?
